SpaceX flight to ISS postponed by one day due to weather
Wednesday, 21 April 2021 13:33
A crewed SpaceX mission to the International Space Station has been postponed by a day due to weather concerns downrange of the launch site, NASA said Wednesday.
Liftoff had been scheduled for Thursday but because of unfavorable conditions along the Atlantic coast, it will now be set for 5:49 am (0949 GMT) Friday.
"For crewed missions we need to look downrange to make sure weather's good for a potential launch escape, and for recovery of the crew," acting NASA Administrator Steve Jurczyk told reporters.
The Crew-2 mission will carry four astronauts in the second routine taxi ride by SpaceX to ISS since the United States resumed crewed space flight, and the first with a European.

Latest: NASA and SpaceX now are targeting 23 April at 10:49 BST (11:49 CEST) for the launch of the Crew-2 mission to the International Space Station due to unfavourable weather conditions along the flight path on Thursday.
French ESA astronaut Thomas Pesquet is returning to the International Space Station on his second spaceflight. The mission, which is called Alpha, will see the first European to launch on a US spacecraft in over a decade. Thomas is flying on the Crew Dragon, alongside NASA astronauts Megan McArthur and Shane Kimbrough, and Japanese astronaut Aki Hoshide.

NASA's NICER probes the squeezability of neutron stars
Wednesday, 21 April 2021 10:49
Matter in the hearts of neutron stars—dense remnants of exploded massive stars—takes the most extreme form we can measure. Now, thanks to data from NASA's Neutron star Interior Composition Explorer (NICER), an X-ray telescope on the International Space Station, scientists have discovered that this mysterious matter is less squeezable than some physicists predicted.
The finding is based on NICER's observations of PSR J0740+6620 (J0740 for short), the most massive known neutron star, which lies over 3,600 light-years away in the northern constellation Camelopardalis. J0740 is in a binary star system with a white dwarf, the cooling remnant of a Sun-like star, and rotates 346 times per second. Previous observations place the neutron star's mass at about 2.1 times the Sun's.
"We're surrounded by normal matter, the stuff of our everyday experience, but there's much we don't know about how matter behaves, and how it is transformed, under extreme conditions," said Zaven Arzoumanian, the NICER science lead at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
Hide and seek: How NASA's Lucy mission team discovered Eurybates' satellite
Wednesday, 21 April 2021 10:49
On Jan. 9, 2020, NASA's Lucy mission officially announced that it would be visiting not seven, but eight asteroids. As it turns out, Eurybates, one of the asteroids along Lucy's path, has a small satellite.
Though searching for satellites is one of the mission's central goals, finding these tiny worlds before Lucy is launched gives the team the opportunity to investigate their orbits and plan for more detailed follow-up observations with the spacecraft.
China is developing plans for a 13,000-satellite megaconstellation
Wednesday, 21 April 2021 09:46
HELSINKI — China is to oversee the construction and operation of a national satellite internet megaconstellation through coordinating the country’s major space actors.
Recent comments by senior officials indicate that plans are moving ahead to alter earlier constellation plans by space sector state-owned enterprises and possibly make these part of a larger “Guowang” or “national network” satellite internet project.

SpaceX and NASA plan to send four astronauts to the International Space Station on Thursday from Florida aboard the first reused Crew Dragon capsule to carry people.
Liftoff of the flight-proven spacecraft, Endeavour, and Falcon 9 rocket is planned for 6:11 a.m. EDT from Complex 39 at Kennedy Space Center.

Wednesday, 21 April 2021 08:31
In 1994, physicist Miguel Alcubierre proposed a radical technology that would allow faster than light travel: the warp drive, a hypothetical way to skirt around the universe's ultimate speed limit by bending the fabric of reality.
It was an intriguing idea - even NASA has been researching it at the Eagleworks laboratory - but Alcubierre's proposal contained problems that seemed insurmounta Space physicist explains why a helicopter flew on Mars is a big deal

Yesterday at 9pm Australian Eastern standard time, the Ingenuity helicopter - which landed on Mars with the Perseverance rover in February - took off from the Martian surface. More importantly, it hovered for about 30 seconds, three metres above the surface and came right back down again.
It may not sound like a huge feat, but it is. Ingenuity's flight is the first powered flight of an air Open Source on Mars: Community powers NASA's Ingenuity Helicopter

The Ingenuity Mars Helicopter departed Earth for its 293 million mile trip to Mars aboard the Perseverance Rover last July. However, Ingenuity's most important journey was only about 10 feet. That's the altitude the small helicopter hovered just above the surface of Mars, marking a major milestone for humanity: the launch was the first powered flight on another planet and proof that it's possibl American Pacific invests in Frontier Aerospace
