Brand-new pics of planet Mercury, just in from the European Space Agency's BepiColombo spacecraft!

Mercury is receding into the distance in this image taken by the ESA/JAXA BepiColombo mission in the early hours of 5 September 2024 as the spacecraft sped by for its fourth of six gravity assist manoeuvres at the planet. The image is a nice teaser of what scientists would like to study in much more detail when BepiColombo starts is main science mission in early 2027. For the first time, BepiColombo saw Mercury’s south pole (top right). Sunlight never reaches the floor of some craters in this region, so despite the planet being very close to the Sun, the land remains freezing cold, making it likely that there is water ice present. The surface of Mercury hosts many fascinating geological features, including four craters close to Mercury’s south pole. The large ring around the south pole indicates the area designated as the south polar region (the equivalent of Earth’s ‘polar circle’). Also in the image are the Mercury Planetary Orbiter’s medium gain antenna (top centre) and magnetometer boom (right).

This is the surface of a comet! Dust is swirling around the surface of Comet 67/P -- captured in 2016 by ESA's Rosetta spacecraft, processing by Jacint Roger Perez.

Still one of the most remarkable scenes in space exploration.

The Euclid space telescope has 2 instruments to analyze light captured by its 1.2 meter 3-mirror Korsch type telescope.

Both instruments have a much wider Field of View compared to JWST and Hubble and have detectors with very large number of pixels.

1. The VISible Imager (VIS) (576 Megapixels) and
2. The Near-Infrared Spectrometer and Photometer (NISP).

The table below shows some key parameters of the instruments.

An #ESA mission to #Jupiter is set to launch tomorrow morning. An #Ariane5 carrying the Jupiter Icy Moons Explorer, or #JUICE, spacecraft rolled out to the launch pad in French Guiana Tuesday for the launch, scheduled for 8:15 a.m. Eastern Thursday. JUICE will arrive at Jupiter in mid-2031, making dozens of flybys of the large moons #Europa, #Ganymede, and #Callisto before going into orbit around Ganymede, studying those icy moons and their subsurface oceans.

Fun Fact #1: #JWST is the LARGEST space telescope ever built! It's so big that the mirrors were folded up to fit in the #ESA #Ariane5 #Rocket that launched it last Christmas

(Yes, this diagram of me standing next to the Hubble and JWST mirrors is to scale!)

A diagram showing how tall Erin is compared to the Hubble and JWST mirrors. Erin is 5.4 feet tall, Hubble has a diameter of 7.9 feet, and JWST has a diameter of 21.3 feet!
