'The line is getting fuzzier': Asteroids and comets may be more similar than we think
Write a comment
As anyone who has ever tried to clean a home knows, ridding yourself of dust is a Sisyphean effort. No surface stays free of it for long. It turns out that space is somewhat similar. Space is filled with interplanetary dust, which the Earth constantly collects as it plods around the sun—in orbit, in the atmosphere, and if it's large enough, on the ground as micrometeorites.
While specimens may not be large, it turns out such dust particles are reforming scientists' conception of asteroids and comets and are enough to reconstruct entire scenes in the history of the solar system.
Fourth flight postponed for Mars Ingenuity helicopter
Write a comment
NASA's Mars Ingenuity helicopter missed its fourth scheduled flight on Thursday, with the space agency blaming a software glitch and vowing to try again the next day.
"The helicopter is safe and in good health," said a statement, adding the rotorcraft had failed to transition to "flight mode."
The team plans to attempt the flight once more on Friday at 10:46 am Eastern Time (1446 GMT) with data expected back at NASA's Jet Propulsion Laboratory around three hours later.
The software issue is thought to be the same one that delayed Ingenuity's maiden voyage, the first powered flight on another planet. Initially scheduled for April 11, the historic feat occurred April 19.
ESA to build second deep space dish in Australia

- ESA, in cooperation with the Australian Space Agency, will construct a new 35-metre, deep space dish antenna at its existing ground station in New Norcia, Western Australia
- The 620-tonne antenna will help ESA provide crucial communication links to its growing fleet of deep space missions
- It will be ESA’s second 35-metre antenna at the site and its fourth in total
- The joint announcement was made during a virtual meeting held between the heads of ESA and the Australian Space Agency on 29 April
Dragon fire

SpaceX’s Falcon 9 rocket carrying the Crew Dragon spits fire as it lifts off from Kennedy Space Center in Florida, 23 April at 05:49 local time. On board are ESA astronaut Thomas Pesquet, NASA astronauts Megan McArthur and Shane Kimbrough, and JAXA (Japan Aerospace Exploration Agency) astronaut Akihiko Hoshide.
The crew of four spent around 23 hours orbiting Earth and catching up with the International Space Station after their launch before docking to the Node-2 Harmony module, marking the start of ESA’s six-month mission Alpha.

Europe's Vega rocket successfully launches
Write a comment
Europe's Vega rocket took off overnight Wednesday from French Guiana with Earth observation satellites on board, six months after losing two satellites.
The rocket left Kourou in French Guiana at around 10:50 pm local time (0150 GMT), with the mission lasting just under two hours.
The launch comes half a year after the operation lost French and Spanish satellites when the rocket fell into the sea on November 17 after a technical malfunction.
The April 28 to 29 launch carried Pleiades Neo 3, the first high resolution satellite of a new Earth observation constellation operated by Airbus.
The rocket is also carrying some lighter payload, including a Norwegian observation microsatellite used to detect radar for maritime navigation.
The Pleiades Neo satellites will offer improved geolocation tools which will help during natural disasters, according to launch provider Arianespace.
The launch is the third this year from the Kourou space centre and the 18th from a Vega.
The Vega rocket is a crucial component of Europe's ambitions to compete in the booming aerospace market, where it faces strong competition from rivals including Elon Musk's SpaceX.

Every day, the sun ejects large amounts of a hot particle soup known as plasma toward Earth where it can disrupt telecommunications satellites and damage electrical grids. Now, scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) and Princeton University's Department of Astrophysical Sciences have made a discovery that could lead to better predictions of
