What happens when a meteor hits the atmosphere
In the heavens above, it's raining dirt. Every second, millions of pieces of dirt that are smaller than a grain of sand strike Earth's upper atmosphere. At about 100 kilometers altitude, bits of dust, mainly debris from asteroid collisions, zing through the sky vaporizing as they go 10 to 100 times the speed of a bullet. The bigger ones can make streaks in the sky, meteors that take our breath a NASA Mission helps solve a mystery: why are some asteroid surfaces rocky?
Scientists thought Bennu's surface was like a sandy beach, abundant in fine sand and pebbles, which would have been perfect for collecting samples. Past telescope observations from Earth had suggested the presence of large swaths of fine-grained material smaller than a few centimeters called fine regolith.
But when NASA's OSIRIS-REx mission arrived at Bennu in late 2018, the mission saw a Technologies and concepts for the satellite navigation systems of the future
Using the best navigation technologies to bring the greatest benefit to their users - this is the what the Galileo Competence Center at the German Aerospace Center is working towards. Together with DLR's institutes, facilities and partners, products are being developed to ensure the continuous improvement of the European Galileo satellite navigation system. The Galileo Competence Center is now o Keeping our eyes on New Horizons
New Horizons remains healthy and continues to send valuable data from the Kuiper Belt, even as it speeds farther and farther from Earth and the Sun. Our team has been extremely busy since I last wrote in the spring. One of the most important activities since then has been ground testing, uploading and flight-testing new software for our Alice ultraviolet spectrometer and our main (Command and Da Mars helicopter Ingenuity approaches 14th flight
The Mars helicopter Ingenuity is ready for a short Martian flight as early as Saturday to test summer weather conditions that have arrived at its location on the Red Planet after two weeks of no communication because of blockage by the sun.
The flight, Ingenuity's 14th, is brief and simple by design. As weather at Jezero Crater gets warmer, the aircraft's rotors must turn faster to achi France launches state-of-art military communications satellite
Paris created a space force command in July 2019, amongst concerns that rival countries were heavily investing in space technology, seen as a new military frontier.
The satellite "is designed to resist military aggression from the ground and in space, as well as interference," French air and space force spokesman Colonel Stephane Spet told AFP.
The Ariane 5 rocket carrying the Syracuse 4A satellite took off from Kourou, in French Guiana late Saturday, with the mission accomplished 38 minutes and 41 seconds after takeoff.
The satellite can survey its close surroundings and move itself to escape an attack.
"Thanks to its state-of-the-art equipment (anti-jamming antenna and digital transparent processor on board), Syracuse 4A will guarantee a high resistance to extreme jamming methods," launch provider Arianespace wrote in its mission description.
Marc Finaud, an expert in weapons proliferation at the Geneva Centre for Security Policy, told AFP the satellite was also protected against the electro-magnetic pulses which would result from a nuclear explosion.
Europe’s data-driven satellite launched
One of the largest telecommunications satellites ever built in Europe has been launched and is on its way to geostationary orbit.
Ariane 5 sets new record on latest launch
Europe’s Ariane 5 has delivered two telecom satellites, SES-17 and Syracuse-4A, into their planned orbits.
Data-driven satellite ready to launch
One of the largest telecommunications satellites ever built in Europe – which will supply high-speed data links for commercial aviation as well as providing connectivity to underserved areas to accelerate digital inclusion – is poised for launch.
