NASA is teaming up with 37 companies to develop the next generation of technologies that could make long-term exploration of the Moon and Mars possible. NASA has chosen 41 proposals from 37 U.S. companies to help develop technologies needed for a sustained human presence on the Moon and eventual crewed missions to Mars. The companies [...]Anil Menon, a NASA flight surgeon, felt crushed nine years ago as his hopes and aspirations collapsed around him.
For the fourth time, he had diligently applied to become an astronaut at the US space agency, seeking to fulfill a lifelong dream. Although he made it to the final round, NASA had once again rejected his application at the end of the grueling process.
"I was so sad, and I admitted defeat," Menon said. "I just did not see a pathway forward. So I pretty much, at that point in time, gave up on being an astronaut. I thought there was a zero percent chance."

A new study favors buried explosions over Hollywood-style head-on impacts.NASA this week released a much-anticipated document, known as a "draft Request for Proposals," that provides some clarity about what it expects from US companies attempting to build privately operated space stations in low-Earth orbit.
The stakes are high with this document, known as a draft RFP. The space agency, publicly, has set an end date for the International Space Station of 2030. Although there is likely to be a two-year extension, time is still running short to build, test, and fly a vehicle as complex as a space station. NASA officials and the US Congress have both said they want to avoid a gap in having a human presence in orbit, and this has created considerable urgency about what comes next.
Nearly five years ago the space agency took a concrete step toward filling this gap, awarding funding to three companies to develop space station concepts. Previously, NASA had also provided $140 million to another space station company, Axiom Space. These Space Act Agreements were intended as a prelude to a second phase of the program, which would award substantially more funding to one or two more companies to proceed into the construction and launch of their space stations. But phase two of the program kept getting delayed, in part because Congress dithered on funding.

The European Space Agency’s (ESA) Euclid Space Telescope has just revealed new evidence for the existence of more than two-and-a-half dozen objects that are among the oldest and most remote in the universe.
These 31 massive objects, known as quasars, rank among the oldest objects astronomers have ever seen, including two that are believed to originate from a period in the universe when our cosmos was only 5% of its current age.
The discoveries, revealed in a new study appearing in the journal Astronomy & Astrophysics, provide a remarkable look at the earliest generations of galaxies, as well as a rare look at the dynamics of the ancient black holes that once powered them.
As some of the brightest objects anywhere in our universe, quasars are remote objects resembling stars in appearance that emit unprecedented amounts of energy. They are the result of creation processes that involve enormous quantities of gas and dust, which spiral into supermassive black holes.
During the gravity-driven inward acceleration process, immense friction causes temperatures that can reach millions of degrees, which generates large amounts of energy. The resulting celestial features produce enough light to outshine entire galaxies.
Despite their brightness, the 31 newest additions to our growing collection of known quasars were difficult for astronomers to spot, given their extreme distances from Earth. The light that documents their ancient presence in the universe has traveled more than 13 billion years to make its way here, causing it to be extremely faint, and thereby very difficult to distinguish from surrounding stars whose light normally outshines them with ease.
A dozen of the newly discovered collection of quasars date to within the first 770 million years our universe existed. Add to that the fact that two of the ancient objects are believed to have formed just 670 million years after the Big Bang—at such ages, these quasars are among the oldest astronomers have ever observed.
The weight of the discoveries goes beyond just record-breaking astronomical observations, since the data they provide could help astrophysicists unravel some of the most enduring mysteries of cosmology. For instance, these quasars could help to reveal answers to questions about how supermassive black holes grew so quickly while the universe was still in its infancy.
Additionally, studying these energetic ancient giants could help to provide new insights into the formation of the earliest galaxies and the evolution of the universe while it was still in its relative infancy.
The recent research, led by the ESA and with contributions from its partners at NASA, has helped to place the Euclid mission in an ideal place to carry out its mission of mapping billions of galaxies. Doing so may help scientists uncover clues about the questions surrounding mysterious dark energy, which is widely believed to be the force behind the accelerating expansion of the cosmos.
Additionally, the Euclid mission’s findings could be pivotal in helping shape the future work of NASA’s Nancy Grace Roman Space Telescope, which will continue the quest to unravel the nature of dark energy and help astronomers understand the nature of the universe at large scales. Additional details about the recent quasar discoveries by Euclid can be found at the ESA’s website and on NASA’s FAQ page.
The new findings were detailed in a recent study, “Euclid: Discovery of 31 new quasars at 6.6 < z < 7.8” published in Astronomy and Astrophysics.

High above the remote Pacific Ocean, about halfway between Hawaii and the northernmost part of Australia, an air-launched rocket fired into space on Independence Day weekend to kick off a weekslong pursuit of a NASA astronomy satellite perilously close to falling out of orbit.
The endeavor to rescue NASA's Swift satellite is the first mission of its kind. NASA put out a call for commercial companies less than a year ago to propose how they could rapidly build and launch a small satellite to latch onto the Swift spacecraft and boost its altitude so that it doesn't come down in a few months.
Katalyst Space Technologies responded with the best offer. NASA awarded the company a contract last September to build and launch a mission to rescue Swift. A little more than nine months later, Katalyst's nearly half-ton Link satellite is safely in orbit. For anyone who follows the space industry, building, testing, and launching a functioning first-of-its-kind satellite of that size in less than a year is a remarkable achievement; it would usually take several years.
