A 1-meter meteoroid (small #asteroid) has been detected and is expected to *safely* strike Earth's atmosphere over northern France between 3:50-4:03 CET.

In the area? Look out for a #ShootingStar!☄️

#Fireball
#Sar2667
This is just the seventh time an #asteroidimpact has ever been predicted before it happens - a sign of the rapid advancements in global asteroid detection capabilities!

📸This was the 6th

Last estimation shows #Sar2667's point of impact getting much closer to the #Rouen area.

A <1m object has struck🌍in the skies above Niagara Falls, becoming a safe #fireball. For just the 6th time, global #asteroid warning systems saw it pre impact, alerting #PlanetaryDefence experts where & when. 'Only' 6x, but this capability is rapidly improving

#AsteroidImpact☄️
Even, observations of the object before it struck!

There are some false reports doing the rounds of a very large asteroid, 2022 AP7, "certain" to strike Earth.

2022 AP7's orbit is well known 100 years into the future and it will not strike Earth or even make a close approach (atleast for a century.)

#AsteroidImpactDebunked☄️❌
This doesn't mean it will strike in 101 years! Only that our #PlanetaryDefence experts calculate asteroid orbits for the next hundred years. Any asteroid with even a tiny chance of impact is added to ESA's #AsteroidRiskList, and becomes the focus of intense observations
New data improves our understanding of its orbit and reduces any uncertainties, after which point it usually becomes clear it will not strike and its removed from the list

After 6 years in orbit, we say goodbye to @CopernicusEU #Sentinel1B and thank you to teams here at ESA’s #MissionControl, who for months have worked tirelessly to troubleshoot the issue that has now resulted in end of mission 👉esa.int/Applications/O…
As the first mission of the @CopernicusEU Programme, Sentinel-1 comprises two satellites orbiting 180 degrees apart, providing all-weather, day-and-night imagery of Earth’s surface, designed, built, launched and flown by @ESA.
The partner satellite, Sentinel-1A, remains healthy in orbit, continuing to deliver high-quality radar images for a multitude of applications.

Our focus is on fast-tracking the launch of Sentinel-1C.

On Monday, for the first time, we performed a set of manoeuvres to avoid a high-risk collision w. #SpaceDebris created in the #Cosmos1408 anti-satellite test last year.

This was a difficult #CollisionAvoidance manoeuvre.👏👏to our #Sentinel1A Control Team & Space Debris Office
#CollisionAvoidance monitoring is unfortunately routine work at #MissionControl, and our teams are well-practiced in reacting to high-risk events.

This near head-on #collision was however unique; the situation evolved rapidly, was tricky to avoid, AND we had <24 hrs warning
Sentinal-1A, part of the @CopernicusEU Sentinel-1 radar observatory providing day-and-night images of Earth’s surface, had its orbit altered by 140 m in order to prevent collision with a debris fragment ~several cm in diameter

A flawless, radiant, #Mercuryflyby

After a flawless flyby of Mercury, @BepiColombo is starting to feel the heat. Image
At 01:34:41 CEST this morning, BepiColombo passed just 199 kilometres from the hot, rocky, innermost planet – the outcome of months of work to get the spacecraft into a precise trajectory for the first rendezvous with its target planet.

#MercuryFlyby
“It was flawless. Everything was perfect from the spacecraft point of view, and as expected, BepiColombo has really started to feel the heat,” explains Elsa Montagnon, Spacecraft #Operations Manager for the mission.

Solar cycle 25: the Sun wakes up🌤️

Experts on the Solar Cycle 25 Prediction Panel recently announced the Sun has officially entered a new cycle, its 25th since we’ve had enough data to reliably recognise them.

👉 esa.int/Safety_Securit…

ESA/NASA SOHO, 2012 - Brendan Gallagher
While we can expect #spaceweather to get more exciting in the next few years, with peak sunspot activity expected in 2025, the panel came to the consensus that this next cycle will be very similar to the previous – both generally weaker than the average solar cycle.

“While small and medium-sized solar storms are more likely during peak solar activity,” says Jussi Luntama, Head of ESA’s #SpaceWeather Office, “its important to remember that individual large solar events can happen any time, independent of we are in the solar cycle.”
