Baseline analysis of 2nd SDG
Almost one in three Indian children under five years will still be stunted by 2022 going by current trends, according to an analysis of the country’s food and nutrition security released on 25 June 2019. Over the last decade, child stunting — which is a measure of chronic malnutrition — has reduced at a rate of about 1% per year, the slowest decline among emerging economies.

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.

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).
