π° World’s 1st Space Station
π Salyut 1 Space Station Launched
π 1st human-crewed space station
π 2,929 orbits around Earth over 175 days
π₯ Tragedy for last crew
π Inhabited for 23 days
On Monday, 19 April 1971, the world’s first ever space station – Salyut 1 – was launched into low Earth orbit by the Soviet Union aboard a Proton-K rocket from the Baikonur Cosmodrome.
The station was designed to conduct scientific experiments and test long-term human habitation in space – equipped with an airlock, telescope mount, and a variety of scientific instruments.
Two missions visited Salyut 1 during it’s operation:
π Soyuz 10, three days after the station’s launch carried a three-person crew, but was unable to dock due to a faulty hatch. The crew were forced to return to Earth after just a few hours.
π Soyuz 11, launched a few months later, the Soyuz crew successfully docked with the station and the three crew members conducted scientific experiments for a record-breaking 23 days before returning to Earth. Sadly, Soyuz 11 suffered a catastrophic failure depressurizing during re-entry – killing all three cosmonauts:
Despite the tragedy associated with the Soyuz 11 mission, Salyut 1 paved the way for future space stations – leading to construction of Mir and the International Space Station, having proved the viability of long-term human habitation in space.
Salyut 1 comprised five compartments:
π¨βπ Transfer: docking for one Soyuz 7K craft (~2m diameter)
π‘ Main: Accommodation, living and control (~4m diameter)
π§° 2x Auxiliary: Control, communications, life-support systems and engines (~2m diameter)
π Orion I Space Observatory: UV telescope, optical and spectrographic imaging. (~2m diameter)
Key stats:
π Measured: 15.8 x 4.15m, with 90mΒ³ of habitable space.
β Launch Mass: 18,900 kg
β‘ Power: 28mΒ² solar panels, split across 4 arrays
π
Days in Orbit: 175 days – 2,929 orbits
π° Distance travelled: 118,602,524 km
π©βπ Days occupied: 23 days
β Deorbit: deorbited intentionally on 11 Oct 1971

π° Surveyor 3 launched
π Second US spacecraft to soft-land on the Moon
πΈ Returned close-up images of lunar surface
π° Conducted key analysis to support Apollo landings
π 1st craft to carry surface-soil scoop
On Monday, 17 April 1967, NASA launched Surveyor 3 – the third lander of the Surveyor Program and only the second US spacecraft to achieve a soft landing on the Moon.
It’s landing was not straight-forward though: reflective rocks confused the lander’s descent radar causing it’s engines to cut-out prematurely – with the lander descending quicker than intended and bouncing twice on the surface before settling with a soft touch-down.
The spacecraft was designed to perform sampling of the surface and was fitted with a number of cameras to image the surface and samples taken. The cameras returned 6,326 pictures between 20 April and 3 May, when it was shutdown for lunar night – and after which could not be reactivated.
These images provided crucial information about the Moon’s geology and topography and included views of the spacecraft, panoramic lunar surveys, the mechanical surface digger at work and of an eclipse of the Sun by the Earth on 24 April.
The craft dug four trenches and collected samples in view of it’s cameras and based on experiments, provided evidence to conclude the lunar surface was solid enough to support the landing of a Lunar Module.
Notably Surveyor 3 became famous when chosen as the landing site for Apollo 12 – who successfully landed within walking distance and photographed the probe, retrieved samples, sensors and equipment – including the cameras which held further images than already returned.

π± US cellular outage after twin solar flares
Two powerful solar flares erupted from the Sun in the last 24 hours – followed shortly by major outages in US cellular coverage – with tens of thousands of outages reported by major carriers AT&T, T-Mobile and Verizon.
Solar Flare Events:
ββπ₯ X1.8 flare at 6:07pm EST on Feb 21
ββπ₯ X1.7 flare at 1:32am EST on Feb 22
It’s not confirmed whether the solar flares were the cause of the outages, but interesting that the reports of outages closely followed these solar events.

π Luna 20 lands on Moon
π Lunar sample return
π Soviet Lunar Exploration
π° Exploration of Moon’s Surface
On Monday, 21 February 1972, the Soviet Luna 20 mission successfully landed on the Moon’s surface – making it the third successful Soviet Lunar sample return mission.
It had launched three days earlier from Baikonur cosmodrome aboard a Proton rocket and entered into lunar orbit on 18 February.
On the 21st February it fired it’s main engine to commence a slow descent to the lunar surface. A second firing reduced it’s velocity for a soft touchdown in a mountainous region known as Terra Apollonius – near Mare Fecunditatis, the ‘Sea of Fertility’.
The craft was equipped with a robotic arm to enable collection of samples of soil and rock for analysis back on Earth.
In the day following the landing, Lunda 20 successfully collected 55g of lunar soil before it’s ascent stage lifted off from the surface.
Luna 20’s spherical capsule parachuted back to Earth three days later – successfully landing on an island in the Karkingir River in Kazakhstan on 25 February 1972.
The Luna 20 mission contributed to the study of the Moon’s geology and helped scientists better understand the Moon’s composition and its history – with the samples shared with scientists around the world – including America, France and Britain.

π Friendship 7 Mission Launched
π¨βπ John Glenn Orbits Earth
π First American to Orbit the Earth
π° Mercury-Atlas 6 Mission
π Milestone in Space Exploration
On Tuesday, 20 February 1962, the Friendship 7 mission blasted off from Cape Canaveral Air Force Station aboard the Mercury-Atlas 6 spacecraft.
Aboard, John Herschel Glenn Jr became the third American in space, and the first American to orbit the Earth – circling it three times in the mission which lasted just under 5 hours. During the trip he travelled at over 17,000 miles per hour.
Glenn’s successful mission demonstrated the feasibility of human spaceflight and was a major boost to America’s space program – which had suffered a number of setbacks while the Soviet program successfully launched the first satellite, Sputnik, in 1957.
Glenn was a distinguished fighter pilot in WW2 and was awarded 6 Distinguished Flying Crosses and 18 Air Medals. In 1957, he had made the first supersonic transcontinental flight before becoming a test pilot.
Later, he joined NASA and the Mercury project – before being selected for Friendship 7. He received the NASA Distinguished Service Medal and the Congressional Space Medal of Honor.
In 1974 he was elected to the US Senate and served for 24 years.
In 1998, at the age of 77, Glenn also became the oldest person to enter Earth’s orbit – aboard Space Shuttle Discovery on mission STS-95.

ποΈββοΈ Alan Shepard Plays Golf on the Moon
π 1st person to play golf on another celestial body
π Oldest person to fly in space or walk on the Moon
π Apollo 14: Third Crewed Lunar Landing
π¬ Scientific Experiments Conducted on Lunar Surface
On Saturday, 6 February 1971, at the end of the Apollo 14 mission, mission commander Alan Shepard made history by becoming the 1st and only person to ever play golf on the moon.
Shepard had been the first American to travel into space – in 1961 aboard the Freedom 7 space capsule, and at the veteran age of 47, Apollo 14 made Shephard the oldest US astronaut to fly, the oldest to walk on the Moon and the first ever person to play golf (or any sport) on another celestial body.
ββ”Miles and miles and miles”
ββAlan Shepard – after striking his second shot.
He had planned the golf shot long in advance – seeking management approval, arranging a customised golf-club with River Oaks Country Club in Houston, carrying out safety tests with NASA’s technical services division – and practicing the shot in his space suit in a local bunker, out of the public eye.
Apollo 14 Crew:
π¨βπ Alan Shephard, Commander
π¨βπ Stuart Roosa, Command Module Pilot
π¨βπ Edgar Mitchell, Lunar Module Pilot
Alongside Edgar Mitchell, Shepard spent approximately 33 hours on the lunar surface – conducting experiments, including a portable nuclear-powered science station and collecting over 42 kilograms of lunar rock and soil samples.
Alan Shepard and the Apollo 14 mission had made history with their success and the fantastic footage, broadcast live drawing in an audience of millions around the world.
Much more recently, in 2001, analysis by the US Golf Association (USGA) using original mission footage and modern stacking techniques – identified the location of the golf balls. Shepard had exaggerated – they had only travelled ~24 and ~40 yards – but who can blame him – an astonishing accolade nonetheless.
Watch the original footage:
