Vanguard 1, launched in 1958 and about the size of a grapefruit, remains the oldest human-made object in Earth orbit; its radio transmitters ceased in 1964, but it continues to circle the planet, helping scientists study orbital dynamics and Earth's shape, with NASA estimating an orbital lifetime of about 240 years (re-entry around 2198) though the date is not precise.
Kosmos 482, a Venus-landing capsule from the Soviet Venera program launched in 1972, failed at launch and spent 53 years in Earth orbit before re-entering on 10 May 2025; its titanium descent capsule, built to withstand Venus’ extreme conditions, may have survived re-entry and landed in the eastern Indian Ocean, though no debris has been confirmed; it stands as the last surviving relic of the Soviet Venus program and a remarkable twist in space history.
In 1946, a captured German V-2 rocket carrying a 35mm DeVry camera reached about 105 kilometers over White Sands, producing the first photographs of Earth from space. The grainy frames showed Earth's curvature and horizon against black sky, predating any formal boundary for space—the Kármán line—by decades. The camera survived the mission, while the rocket and many of its builders did not, and the achievement is often credited to Clyde Holliday and the Johns Hopkins APL team who adapted gear meant for other uses to peer into the upper atmosphere.
In Oct 1959, Luna 3, a small Soviet spacecraft, flew behind the Moon, captured 29 35mm photographs, developed the film onboard, and scanned/transmitted the images back over about 480,000 km. The resulting frames—though grainy—gave the first view of the Moon’s far side (covering roughly 70% of it; 17 frames are commonly cited as successfully transmitted), revealing a terrain with fewer maria and more craters and laying the groundwork for future lunar mapping and exploration.
Galileo’s 1995 Jupiter probe descended into the gas giant, transmitting for about 58 minutes before the harsh pressures ended the signal; it provided the first in-situ measurements of a giant planet’s atmosphere—temperatures, pressures, densities, chemistry, and cloud structure—revealing a drier-than-expected hot-spot region and hotter, denser conditions, while highlighting the limitation that a single descent cannot characterize the entire planet.
On December 15, 1970, the Soviet lander Venera 7 became the first object to transmit from the surface of another planet, delivering about 23 minutes of data before its batteries overheated in Venus’s ~475°C heat and 90 atm pressure; a misfired parachute left the antenna poorly oriented, masking the success until a later tape review confirmed the surface transmission via temperature telemetry. Venus’s extreme environment has limited long-duration landers, a pattern the Venera program confirmed with successive missions, while future Venus exploration emphasizes orbiters and short descent probes (e.g., DAVINCI, EnVision, VERITAS) rather than long-lived landers.
In May 1969, Apollo 10 crew Stafford, Young and Cernan achieved the fastest human speed on reentry—36,397 ft/s (about 39,937 km/h)—during their lunar-return trajectory. The record endures because no crewed mission has left Earth orbit since Apollo 17, and subsequent flights have not surpassed that reentry velocity. Artemis plans aim to return humans to the Moon with comparable speeds, but thus far only the uncrewed Artemis I reentry reached about 39,400 km/h, keeping Apollo 10’s speed record intact as a landmark of lunar-flight physics.
A historic 26-meter radio telescope in North Carolina, originally built for NASA's space tracking in 1962 and later used for military and intelligence purposes, is now for sale. The Pisgah Astronomical Research Institute (PARI) owns the site, which continues to support space research and education, and is seeking partners to help preserve its mission while exploring new uses, including private sector collaborations.
The episode commemorates the 60th anniversary of the Mariner 4 mission, which was the first to successfully send back images of Mars, revealing its dry, cratered surface and changing our understanding of the Red Planet.
The article discusses the rejected Apollo-Soyuz mission patch designed by Paul Calle, the history of the various patches used for the mission, and a recent revival of Calle's original design by his son Chris Calle, who aims to bring the artwork back to life through limited-edition embroidered patches.
Billionaire Jared Isaacman, known for his role in the Inspiration4 mission, has made the largest private donation in the U.S. Space Force Historical Foundation's history. The funds will support the restoration of rare missile-related artifacts and upgrades at the Cape Canaveral Space Force Museum. The donation will help preserve significant pieces like the Subroc missile, Big Shot Shroud, and ARCAS weather rocket launcher, and will also fund new exhibits and future expansions.
United Launch Alliance (ULA) launched its final Delta IV Heavy rocket, marking the end of a 64-year history of Delta rocket launches. The rocket carried a classified payload for the U.S. National Reconnaissance Office (NRO) and ignited a unique spectacle due to hydrogen buildup in the flame trench. ULA is retiring the Delta IV in favor of its newly introduced Vulcan rocket, designed specifically for national security space missions. The Delta rocket family has a storied legacy, with various versions and configurations contributing to significant space exploration milestones, and only a few Delta rockets are preserved in museums and rocket parks today.
Space Center Houston, the visitors' hub for NASA's Johnson Space Center, is filled with space history, including a flown Mercury program capsule, the Gemini 5 spacecraft, and Apollo 17's command module. The museum also features a moon rock display, a lunar module test vehicle, and a lunar roving vehicle trainer. The shuttle carrier aircraft, which used to ferry the spacecraft between servicing sites on Earth, is also on display. The Artemis program exhibit includes a ginormous moon model and a picture of Jessica Watkins, the first Black woman astronaut to complete a long-duration mission. The Artemis 2 crew, which will fly around the moon no sooner than November 2024, was announced on April 3.
As Starship's orbital test flight approaches, it may take multiple attempts to get Booster 7 and Ship 24 off the ground. This article looks at some of the aborts and scrubs that have occurred in space history, including those of the Saturn V, N1, Energia, Space Shuttle, and SLS. Starship has already experienced on-pad aborts during suborbital tests, but no orbital launch attempt has been made yet. The vehicle is equipped with an autonomous flight termination system, meaning it will destroy itself if specific parameters reach a critical threshold.
