Thanks to CTOnews.com netizens Yu Xue Zhaidu, new soft media friends 2xrpri, South China Daniel Wu for the delivery of clues! CTOnews.com, July 2, Beijing time, 23:12 on July 1, 2023, SpaceX used Falcon 9 to launch the Euclid (Euclid) space telescope to the solar-terrestrial L2 transfer orbit for ESA ESA from SLC-40, and successfully completed the recovery.

The launch used the Falcon 9 Block5 rocket (Core stage B1080-2); it successfully landed on the barge ASOG eight minutes and 40 seconds after take-off; about 18 minutes after take-off, the secondary ignition of the second stage was completed; about 41 minutes after take-off, the star and arrow separated, and the satellite successfully embarked on the journey to Lagrange L2, and the launch mission was a complete success.

One month after launch, the telescope is expected to arrive near solar-terrestrial L2 point (also known as solar-terrestrial Lagrangian L2 point), about 1.5 million km from Earth, and enter the Halo orbit around solar-terrestrial L2 point, followed by a two-month test and calibration of scientific payloads.

It is worth mentioning that the Euclid telescope was originally planned to be launched by the Russian Federation 2 ST-B, but was later abandoned for well-known reasons and was eventually launched by a SpaceX Falcon 9 rocket.

▲ Source: ESA according to reports, the $1.6 billion space telescope, which is equipped with two imaging devices (visible light camera + near infrared spectrometer), aims to draw a three-dimensional image of the 600MP universe covering one CTOnews.com three-day region by observing billions of galaxies 10 billion light-years away, and explore how the universe has evolved over the past 10 billion years. To this end, more than 1000 scientists around the world have formed a huge research team.

The core of Euclid's investigation is dark matter and dark energy. Although dark matter is invisible, its gravitational pull on galaxies can be detected.

In addition, astronomers plan to investigate unsolved mysteries such as why the universe is expanding. To better understand these phenomena, Euclid's cosmic images will take six years to draw in detail after the first three months of data calibration, with more than 2000 scientists from Europe, Canada, Japan and the United States participating in the study.

The telescope will also provide data to confirm whether Albert Einstein's theory of gravity is correct. It is said that Einstein's theory has never been tested on the distance and scale of the data collected by Euclid.

It is reported that the launch mission is:

◆ 1st launch of Falcon 9 in July 2023 (all successful)

◆ 2023 Falcon 9 rocket 42nd launch (all successful)
