Two galaxies colliding
NASA and European Space Agency’s (ESA) Hubble Space Telescope has just captured images of two luminescent galaxies catalogued as UGC 2369. The telescope was able to capture mutual gravitational attraction between both the galaxies. Interaction between galaxies is not an uncommon event, however, two similarly sized ones merging is one of a kind.

ISRO
rocket debris on Australian shore
GS Paper - 3 (Space Technology)

A large object found on the shores of western Australia a couple of weeks ago has been confirmed to be the debris of an Indian Space Research Organisation (ISRO) rocket, the Australian Space Agency said. ISRO has agreed with the assessment, saying the debris could be from one of its Polar Satellite Launch Vehicle (PSLV) rockets. The ISRO said the agency was still to decide on the future course of action.

Are such incidents normal?

Junk from space objects falling to the earth are not unheard of. Most such incidents involve relatively small fragments from rockets that survive the friction of the atmosphere.
These usually do not make big news, also most of the time the space junk falls into oceans thus posing little danger to human populations.
But there have been a few highly publicised falls as well. In recent times, a large chunk of a 25-tonne Chinese rocket fell into the Indian Ocean in May 2021.
The most famous such case remains that of the Skylab space station, a predecessor to the currently operational International Space Station, which disintegrated in 1979.
Large chunks from this disintegration fell into the Indian Ocean, some of them falling on land in Western Australia.

Isn’t it dangerous?

The threat to life and property from falling space junk is not negligible. Even when falling into the oceans, which is more likely since 70 per cent of the earth’s surface is ocean, large objects can be a threat to marine life, and a source of pollution.
However, there are no recorded incidents of these falling objects causing any appreciable damage anywhere on the earth. When they have dropped over land, so far, it has been over uninhabited areas.

What happens if these objects cause damage?

There are international regulations governing space debris, which include junk falling back on the earth.
Most space-faring countries are signatories to the Convention on International Liability for Damage Caused by Space Objects.
This convention is one of the several international agreements that complement the Outer Space Treaty, the overarching framework guiding the behaviour of countries in space.
The Liability Convention deals mainly with damage caused by space objects to other space assets, but it also applies to damage caused by falling objects on earth.
The Convention makes the launching country “absolutely liable” to pay compensation for any damage caused by its space object on the earth or to a flight in air. The country where the junk falls can stake a claim for compensation if it has been damaged by the falling object.
In the current case, if the PSLV junk had caused any damage in Australia, India could have been liable to pay compensation, even if the object fell into the ocean and was then swept to the shores.
The amount of compensation is to be decided “in accordance with international law and the principles of justice and equity”.
This provision of the Convention has resulted in compensation payment only once so far — when Canada sought damages from the then Soviet Union, for a satellite with radioactive substance that fell into an uninhabited region in its northern territory in 1978. The Soviet Union is reported to have paid 3 million Canadian dollars.

Nuclear-powered
rocket cut travel time to Mars
GS Paper - 3 (Energy)

In less than three years, NASA could be testing a nuclear rocket in space. The space agency and the Defense Advanced Research Projects Agency, or DARPA, announced that Lockheed Martin had been selected to design, build and test a propulsion system that could one day speed astronauts on a trip to Mars. The program is named DRACO, short for the Demonstration Rocket for Agile Cislunar Operations.

What if a spacecraft could get to Mars in half the time it currently takes?

Every 26 months or so, Mars and Earth are close enough for a shorter journey between the worlds. But even then it is a pretty long trip, lasting seven to nine months. For most of the time, the spacecraft is just coasting through space.
But if the spacecraft could continue accelerating through the first half of the journey and then start slowing down again, the travel time could be slashed.
Current rocket engines, which typically rely on the combustion of a fuel like hydrogen or methane with oxygen, are not efficient enough to accomplish that; there is not enough room in the spacecraft to carry that much propellant.
But nuclear reactions, generating energy from the splitting of uranium atoms, are much more efficient.
The DRACO engine would consist of a nuclear reactor that would heat hydrogen from a chilly minus 420 degrees Fahrenheit to a toasty 4,400 degrees, with the hot gas shooting from a nozzle to generate thrust. Greater fuel efficiency could speed up journeys to Mars, reducing the amount of time astronauts spend exposed to the treacherous environment of deep space.
Nuclear propulsion could also have uses closer to home, which is why DARPA is investing in the project. The technology may allow rapid maneuvers of military satellites in orbit around Earth.

Flashback

Nuclear propulsion for space is not a new idea. In the 1950s and 1960s, Project Orion — financed by NASA, the Air Force and the Advanced Research Projects Agency — contemplated using the explosions of atomic bombs to accelerate spacecraft.
At the same time, NASA and other agencies also undertook Project Rover and Project NERVA, efforts that aimed to develop nuclear-thermal engines similar in concept to those now being pursued by the DRACO program.
A series of 23 reactors were built and tested, but none were ever launched to space. Until the end of this program in 1973, NASA had contemplated using nuclear reactors to propel space probes to Jupiter, Saturn and beyond, as well as to provide power at a lunar base.
The technical capabilities, including early safety protocols, remain viable today, Tabitha Dodson, the DRACO project manager, said in a news briefing on 2 August 2023.
A key difference between NERVA and DRACO is that NERVA used weapons-grade uranium for its reactors, while DRACO will use a less-enriched form of uranium. The reactor would not be turned on until it reached space, part of the precautions to minimize the possibility of a radioactive accident on Earth.

Russia’s Luna-25 crashes
GS Paper - 3 (Space Technology)

Russia’s Moon mission ended in failure after its spacecraft Luna-25 spun out of control and crashed into the moon, Russian space agency Roscosmos said on 20 August 2023.

What happened to Luna-25?

Luna-25 was supposed to land on the Moon on 21 August 2023, days ahead of India’s Chandrayaan-3. Its intended landing site was close to Chandrayaan-3’s, near the lunar south pole.
The crash was confirmed a day after Roscosmos reported an “abnormal situation” which its specialists were analysing.
The space agency had said on 19 August 2023 that it had lost contact with the aircraft as it was shunted into pre-landing orbit.
On 19 August 2023, in accordance with the flight program of the Luna-25 spacecraft, an impulse was provided for the formation of its pre-landing elliptical orbit.
Communication with the Luna-25 spacecraft was interrupted. The measures taken on 19 and 20 August 2023 to search for the device and get into contact with it did not produce any results. According to the results of the preliminary analysis, due to the deviation of the actual parameters of the impulse from the calculated ones, the device switched to an off-design orbit and ceased to exist as a result of a collision with the lunar surface, Roscosmos said.
The space agency also said, A specially formed interdepartmental commission will deal with the issues of clarifying the reasons for the loss of the Moon [mission].
What was the Luna-25 mission?

Although launched on 10 August 2023, almost a month after Chandrayaan-3’s launch on 14 July, Luna-25 rode on a powerful rocket to reach the lunar orbit in just six days.
It was supposed to land on the lunar South Pole before Chandrayaan-3, and its success would have made Russia the first country to do so. Luna-25’s mission life was for one year, and its lift-off mass was 1,750 kg.
It did not carry a rover, but had eight payloads mainly to study the soil composition, dust particles in the polar exosphere, and most importantly detect surface water on the moon.
Significance

The failure of Luna-25 underlines how tricky soft-landings on the Moon are, and echoes India’s heartbreak of 2019.
Since 1976, there has been just one country, China, which has been successful in getting its spacecraft to soft land on the moon.
It has done that twice, with Chang’e 3 and Chang’e 4. All other attempts in the last ten years, by India, Israel, Japan and now Russia, have remained unsuccessful.
If Chandrayaan-3 is able to land successfully, India would become just the fourth country in the world, after the United States, the erstwhile Soviet Union and China, to have landed a spacecraft on moon, and the first-ever to land close to the lunar south pole.

Crew-7 mission to space station
GS Paper - 3 (Space Technology)

Four astronauts from four countries, including the US, Denmark, Japan, and Russia, launched aboard a SpaceX rocket towards the International Space Station (ISS) from NASA’s Kennedy Space Center in Florida. This was the first US take-off in which all the astronauts atop the spacecraft belonged to a different country — until now, NASA had always included two or three of its own on its SpaceX flights. The mission has been known as Crew-7.

Why has such a diverse group of astronauts gone to the ISS?

The Crew-7 mission is a result of the ongoing cooperation among different countries in space, especially since the launch of the space station in 1998.
The International Space Station Program involves the US, Russia, Canada, Japan, and the participating countries of the European Space Agency, and is one of the most ambitious international collaborations ever attempted.
The program “brings together international flight crews, multiple launch vehicles, globally distributed launch, operations, training, engineering, and development facilities; communications networks, and the international scientific research community”.
What is the mission?

The Crew-7 is the eighth flight operated by NASA and Elon Musk-owned SpaceX as part of the agency’s commercial crew program, which has been taking astronauts to the ISS since SpaceX’s first crewed mission in 2020.
During their stay at the space station, the Crew-7 astronauts will conduct more than 200 science experiments and technology demonstrations to prepare for missions to the Moon, Mars, and beyond.
The research will include a collection of microbial samples from the exterior of the space station.
The team will also analyse how sleeping in the microgravity environment differs from Earth by examining astronauts’ brain waves while they sleep.
Yet another experiment will look at the formation of biofilms in wastewater on the space station, which could be key to finding better ways to recycle water for drinking and hygiene while in space (Yes, astronauts have long used recycled sweat and urine to drink and shower on the station).

The points can be used as ‘parking spots’ for spacecraft in space to remain in a fixed position with minimal fuel consumption.
They have been named after Italian-French mathematician Joseph-Louis Lagrange (1736-1813), who was the first one to find the positions. So, between the Earth and the Sun, a satellite can occupy any of five Lagrangian points. “Of the five Lagrange points, three are unstable and two are stable. The unstable Lagrange points – labelled L1, L2, and L3 – lie along the line connecting the two large masses. The stable Lagrange points – labelled L4 and L5 – form the apex of two equilateral triangles. The L4 and L5 are also called Trojan points and celestial bodies like asteroids are found here.

JAXA successful launch lander SLIM on Moon
GS Paper - 3 (Space Technology)

Indian Space Research Organisation (ISRO) congratulated Japan Aerospace Exploration Agency (JAXA) on 7 September 2023 for the successful launch of the Smart Lander for Investigating Moon (SLIM).

More about SLIM

Japan launched its H-IIA rocket on 7 September 2023 carrying the JAXA Moon lander which is scheduled to land on the Moon early next year.
The rocket carried an X-ray telescope called the X-Ray Imaging and Spectroscopy Mission (XRISM), which will study the origins of the universe. XRISM will measure the composition and speed of intergalactic space.
This space mission aims to help scientists to understand celestial object formation and the universe's creation.
This mission was conducted in collaboration with NASA, and it will involve studying light at various wavelengths, temperature assessments, and analysing the shapes and brightness of celestial objects.
Onboard the rocket is JAXA's Smart Lander for Investigating Moon (SLIM) spacecraft also known as the "Moon Sniper" for its precision landing technology.
This launch follows India's recent achievement of becoming the fourth nation to successfully land a spacecraft on the Moon with its Chandrayaan-3 mission. The launch comes two weeks after India successfully landed Vikram lander on the lunar South Pole.
Japan had previously experienced two unsuccessful attempts to land on the Moon. The first resulted in a loss of contact with a lander carried by a NASA rocket, and the second, an attempt by a Japanese start-up, ended in a crash during the lunar descent in April.
