Space acquisition nominee: Satellites must be defended, ‘the economy depends on space’
Thursday, 17 February 2022 18:36
Frank Calvelli, nominated by President Biden to be assistant secretary of the Air Force for space acquisition and integration, said Feb. 17 that the United States needs to move quickly to protect satellites so they can be “counted on during times of crisis and conflict.
Wanted: your new ideas for navigation
Thursday, 17 February 2022 13:52
It is hard to overstate the importance of knowing precisely where (and when) you are and where you are going within today’s economy and society. Do you have a promising idea to improve the current positioning state-of-the-art? Then ESA’s navigation-focused NAVISP research programme wants to hear from you, before the end of March.

Gaia reveals a new member of the Milky Way family
Thursday, 17 February 2022 07:00

Our galaxy, the Milky Way, began forming around 12 billion years ago. Since then, it has been growing in both mass and size through a sequence of mergers with other galaxies.
Perhaps most exciting is that this process has not quite finished, and by using data from ESA’s Gaia spacecraft, astronomers can see it taking place. This in turn allows to reconstruct the history of our galaxy, revealing the ‘family tree’ of smaller galaxies that has helped make the Milky Way what it is today.
The latest work on this subject comes from Khyati Malhan, a Humboldt Fellow at the
How to design a sail that won't tear or melt on an interstellar voyage

Astronomers have been waiting decades for the launch of the James Webb Space Telescope, which promises to peer farther into space than ever before. But if humans want to actually reach our nearest stellar neighbor, they will need to wait quite a bit longer: a probe sent to Alpha Centauri with a rocket would need roughly 80,000 years to make the trip.

Thursday, 17 February 2022 04:47
Vaya Space announced the successful launch of its hybrid rocket from Mojave, California on January 29th, 2022 operating under an existing FAA waiver. The suborbital flight demonstrated its hybrid rocket design using 3D printed fuel grains created from recycled thermoplastics. This launch paves the way for rapid acceleration of Vaya Space's go-to-market strategy as the Company scales for producti Sols 3388-3390: Pediment Passage
Thursday, 17 February 2022 04:47
Curiosity is advancing westward through a largely boulder-strewn channel that is leading us toward the Greenheugh Pediment. The Pediment is where our rover will spend the next many months, as we turn back uphill to the south and continue our ascent up Mt. Sharp. Despite it being quite craggy in our current location, we did have to drive over a large sand patch to get to our current parking locat Testing rocks on Earth to help NASA's Perseverance work on Mars
Thursday, 17 February 2022 04:47
When NASA's Perseverance Mars rover tried to collect its first rock core sample last August, the outcome presented a puzzle for the mission team: The rover's sample tube came up empty. But why?
Not long after, Perseverance successfully gathered a sample the size of a piece of chalk from a different rock. The team concluded that the first rock they had chosen was so crumbly that the rover's JILA atomic clocks measure Einstein's general relativity at millimeter scale
Thursday, 17 February 2022 04:47
JILA physicists have measured Albert Einstein's theory of general relativity, or more specifically, the effect called time dilation, at the smallest scale ever, showing that two tiny atomic clocks, separated by just a millimeter or the width of a sharp pencil tip, tick at different rates.
The experiments, described in the Feb. 17 issue of Nature, suggest how to make atomic clocks 50 times NASA's IXPE sends first science image
