(Inside Science) -- In long distance space travel, traditional rockets would eventually run out of fuel. There is an alternative: Since as early as the 19 th century, scientists have dreamed of building spacecraft with light sails that can accelerate slowly, but for a much longer time, by catching the light from Earth's sun or, in more modern designs, powerful ground-based lasers.
Researchers have now introduced a lab-tested design for a laser-driven light sail that can self-stabilize and could potentially ride a laser beam all the way out of our solar system.

As We Enter a New Decade, Space Food Has Suddenly Rocketed Into Renewed Prominence
Whether it was the idea of astronauts drinking Tang or reading stories about how the Space Shuttle crews would prepare their meals and then try to eat in the microgravity environment of space, I couldn’t get enough info about how human space travelers fed themselves.
In a way, it was the very idea that these rigorously trained astronauts flying billion dollar equipment hundreds of miles above the earth’s surface still had to find time to prepare a meal that made the idea of space travel that much more relatable to a kid like me.
How big is NASA's Space Launch System? Check these new images - al.com
NASA has been telling us how big the Space Launch System (SLS) rocket will be when finally assembled on the launch pad. "It's the biggest rocket the agency has built since the Apollo V moon rocket," the space agency says frequently.
New pictures taken over the holidays give the clearest understanding of just how large that is. NASA recently completed assembling the SLS core stage including its four space shuttle main engines and the liquid hydrogen and oxygen tanks that will feed them.
SpaceX: Elon Musk's Crew Dragon demo video teases 5 key innovations | Inverse
On December 30, the firm shared a video via YouTube of its planned Crew Dragon capsule launching two astronauts into space. The capsule docks with the International Space Station, before successfully returning to Earth. The three-minute video demonstrates both the planned crew capsule, as well as a multitude of other advancements including a Tesla vehicle and a high-quality spacesuit.
If all goes to plan, the video should become a reality before long. CEO Elon Musk claimed in October 2019 that the first "Demo-2" flight, which will send two astronauts on a test mission, could launch as soon as the first quarter of 2020. The capsule is part of NASA's Commercial Crew program, aimed at bringing manned launches back to the United States.

India Is Preparing for Its First Manned Space Mission in 2022 | Travel + Leisure
Chairman of the Indian Space Research Organisation (ISRO) Kailasavadivoo Sivan at a press conference announcing ISRO's plans for 2020 including the progress in 'Chandrayaan 3' moon mission and 'Gaganyaan' mission for putting an Indian astronaut into space, during a press conference.
India is preparing to send astronauts into space, which, if successful, would make them the fourth country in the world to do so.
A total of four candidates from the country have been chosen for the first manned mission, which is planned for 2022, NPR reported on Wednesday. The candidates are expected to start training in Russia in a few weeks.

With Space Force, Congress Hands Trump a Major Victory - Truthdig
Donald Trump, who will go down in history as the most reviled president of all time, has just won a major victory in the creation of a sixth branch of the military: Space Force. Trump will be able to claim credit for a serious milestone — with the smooth cooperation of both major parties.
On Dec. 20, Trump signed the 2020 National Defense Authorization Act after both chambers of Congress passed the bill. A major provision of the law was the creation of Space Force, a military unit the president was openly seeking. His achievement was apparently won in exchange for conceding to Democrats’ demands for paid parental leave for federal employees.
