in 1966, the first Orbiting Solar Observatory (OSO) was launched. The OSO 1 was the first satellite to have pointed instruments and onboard tape recorders for data storage.

The objectives of the OSO satellite series were to perform solar physics experiments above the atmosphere during a complete solar cycle and to map the celestial sphere for direction and intensity of UV light, X-rays, and gamma radiation.

The OSO 1 platform consisted of a sail section, which pointed two experiments continuously toward the sun, supplying power to the experiments from the solar batteries and rechargeable chemical batteries; and a wheel section, which spun about an axis perpendicular to the pointing direction of the sail and carried seven experiments.

Happy new year! On Mars at least.

7th February marked the beginning of a new year on the Red Planet. This is now "Mars Year 36" on Mars as tracked by humans on Earth.
The Martian new year begins as three different missions are closing in on the Red Planet. The United Arab Emirates' Hope orbiter is due to arrive in orbit around Mars today (Feb. 9). A day later, China's Tianwen-1 mission is also expected to enter orbit. Tianwen-1 is carrying three different probes: an orbiter, lander and small rover. Then on Feb. 18, NASA's Mars rover Perseverance will make a daring landing via a parachute and sky crane in a region known as Jezero Crater. So, it's going to be a busy year on the Red Planet.

Our moon is moving away from Earth at a rate of 1.6 inches (4 cm) per year!
Scientists do believe that eventually, the Moon will move out of the field of Earth’s gravity; however, this won’t happen for billions of years to come.

in 1966 Luna 9, an uncrewed space mission of the Soviet Union's Luna programme became the first spacecraft to achieve a lunar soft landing and to transmit photographic data from the Moon's surface to Earth.
The probe also proved that the lunar surface could support the weight of a lander and that an object would not sink into a loose layer of dust as some models predicted. Luna 9 launched on 31 January 1966 at 11:41 UT (14:41 Moscow time) from Baikonur Cosmodrome and reached the Moon on 3 February.

A small rocket billed as the world's first commercial booster powered by biofuel has launched from Maine.

The Brunswick-based startup bluShift Aerospace launched its first rocket prototype, called Stardust 1.0, on Sunday (Jan. 31), despite freezing temperatures and two false starts. The rocket didn't reach space (or even a mile up), but marked a major milestone for a company aiming to launch bespoke missions tailored for tiny satellites.

in 1908, Philibert Jacques Melotte discovered the Pasiphae, a retrograde irregular satellite of Jupiter, with the Greenwich Observatory's 30-inch Cassegrain telescope.

It received the provisional designation 1908 CJ, as it was not clear whether it was an asteroid or a moon of Jupiter. The recognition of the latter case came by April 10.

Pasiphae did not receive its present name until 1975 before then, it was simply known as Jupiter VIII. It was sometimes called "Poseidon" between 1955 and 1975.

SpaceX successfully launched an ambitious rideshare mission as one of its veteran boosters hoisted 143 small satellites — a new record for a single rocket — into space before nailing a landing at sea.

The two-stage Falcon 9 rocket lifted off Sunday morning (Jan. 24), soaring into a blue sky dotted with clouds at 10 a.m. EST (1500 GMT) from the Space Launch Complex 40 at Cape Canaveral Space Force Station here in Florida.

In 2011, astronomers discovered the largest and farthest reservoir of water ever detected in the universe. The water, equivalent to 140 trillion times all the water in the world's ocean, surrounds a huge, feeding black hole, called a quasar, more than 12 billion light-years away.

in 1926 Robert H Goddard tested the first Liquid Fuelled Rocket. This was a prototype model.
The actual flight model was tested on 8th March 1926.
The rocket travelled for 2.5 secs at a speed of about 60 mph, reaching an altitude of 41 feet and Landing 184 feet away.

1st Starlink satellites launch of 2021

SpaceX is targeting Tuesday, January 19 for its seventeenth Starlink mission, which will launch 60 Starlink satellites from Launch Complex 39A (LC-39A) at Kennedy Space Center. The instantaneous window is at 8:23 a.m. EST, or 13:23 UTC.

The space company will send up a Falcon 9 rocket for its 17th Starlink mission.

About 60 Starlink internet satellites will be sent into orbit, joining about 1,000 others. The goal is to provide worldwide, space-based broadband coverage.

You can watch the launch live here (https://youtu.be/84Nct_Q9Lqw) and on the Space.com homepage, courtesy of SpaceX, beginning about 15 minutes before liftoff. You can also watch the launch directly via SpaceX (https://www.spacex.com/launches/index.html).
