BepiColombo mission shares stunning image of Mercury flyby

The European and Japanese team behind the BepiColombo mission to Mercury has shared the first image of the spacecraft’s recent flyby of the distant planet.

The black-and-white image shows the planet in incredible detail, its surface pockmarked by numerous craters from billions of years of asteroid and comet bombardment.

Hello again Mercury!

Here's a first look from today's #MercuryFlyby capturing such an amazing array of the planet's rich geological features 🤩https://t.co/hC6TfMmCy1#ExploreFarther pic.twitter.com/7WkYiGU0Kp

It was captured by the mission’s Mercury Planetary Orbiter from around 570 miles (920 kilometers) above the planet’s surface on June 23. The European Space Agency (ESA) noted that the spacecraft made an even closer approach just five minutes before the image was taken, coming within just 124 miles (200 kilometers) of Mercury’s surface.

Parts of the Mercury Planetary Orbiter are also visible in the image. The spacecraft’s magnetometer boom, for example, can be seen running from bottom-left to top-right, and a small part of the medium-gain antenna at bottom-right is also within the frame.

Look toward the bottom-left of the image and you’ll be able to spot the 124-mile-wide (200 kilometer). multi-ringed basin, part of which is obscured by the magnetometer boom.

This week’s flyby is the second performed by the Mercury Planetary Orbiter and comes eight months after the first, which captured an image from about 620 miles (1,000 kilometers) above the planet’s surface.

“Even during fleeting flybys, these science ‘grabs’ are extremely valuable,” said Johannes Benkhoff, ESA’s BepiColombo project scientist. “We get to fly our world-class science laboratory through diverse and unexplored parts of Mercury’s environment that we won’t have access to once in orbit, while also getting a head start on preparations to make sure we will transition into the main science mission as quickly and smoothly as possible.”

The main science mission will see ESA’s Mercury Planetary Orbiter — together with Japan’s Mercury Magnetospheric Orbiter, which is also part of the BepiColombo mission — analyze Mercury’s core-to-surface processes, magnetic field, and exosphere in a bid to learn more about the origin and evolution of a planet that orbits so close to its parent star.

ESA said the observations will be “key to understanding solar wind-driven magnetospheric processes, and BepiColombo will break new ground by providing unparalleled observations of the planet’s magnetic field and the interaction of the solar wind with the planet at two different locations at the same time.”

The orbiter is currently beaming additional images to Earth, with the team expected to share them online on Friday morning. All images will be released to the public in the Planetary Science Archive on Monday, June 27, ESA confirmed.

This is how the world ends: swallowed or shredded by a dying sun
Clumps of debris from a disrupted planetesimal are irregularly spaced on a long and eccentric orbit around the white dwarf. Individual clouds of rubble intermittently pass in front of the white dwarf, blocking some of its light. Because of the various sizes of the fragments in these clumps, the brightness of the white dwarf flickers in a chaotic way.

One of the stranger facets of astronomy is contemplating what the fate of the Earth will be when the sun dies. Eventually, in billions of years' time, the sun will inevitably run out of fuel and enter the final stages of its life, puffing up to a huge size called a red giant. When it does this, the sun will swallow Mercury and Venus completely -- but the status of Earth is not quite so certain.

Researchers recently studied the status of dead stars called white dwarfs, which are the cores that remain after a red giant collapses. This gives a glimpse at what our own solar system will look like in 5 billion years. Earth may or may not be engulfed by the sun, but it certainly won't be habitable any longer.

Hubble spots a bright galaxy peering out from behind a dark nebula
The subject of this image taken with the NASA/ESA Hubble Space Telescope is the spiral galaxy IC 4633, located 100 million light-years away from us in the constellation Apus. IC 4633 is a galaxy rich in star-forming activity and also hosts an active galactic nucleus at its core. From our point of view, the galaxy is tilted mostly towards us, giving astronomers a fairly good view of its billions of stars.

A new image from the Hubble Space Telescope shows a galaxy partly hidden by a huge cloud of dust known as a dark nebula. The galaxy IC 4633 still shines brightly and beautifully in the main part of the image, but to the bottom right, you can see dark smudges of dust that are blocking the light from this part of the galaxy.

Taken using Hubble's Advanced Camera for Surveys (ACS) instrument, the image also incorporates data from the DECam instrument on the Víctor M. Blanco 4-meter Telescope, which is located in Chile. By bringing together data from the space-based Hubble and the ground-based DECam, astronomers can get a better look at this galaxy, located 100 million light-years away, and the dark dust partially obscuring it.

Watch NASA begin testing its Orion capsule for lunar flyby
NASA starts testing the Orion capsule for the Artemis II mission.

NASA has started testing the Orion spacecraft that will take four astronauts on a voyage around the moon as part of the Artemis II mission currently scheduled for 2025.

The space agency shared a video (below) showing the Orion capsule being transported to an upgraded vacuum chamber inside the Operations and Checkout Building at NASA’s Kennedy Space Center in Florida. There, it will undergo electromagnetic compatibility and interference testing.
