Space Missions — Every Major Mission from Sputnik to the 2040s
UPDATED Apr 12 2026 08:30A comprehensive guide to humanity's exploration of space — from the first satellite to robotic rovers on Mars, gravitational wave detectors, and the missions currently en route to the outer solar system. Covers NASA, ESA, Roscosmos, ISRO, CNSA, JAXA, SpaceX, and commercial operators.
1. Overview
As of 2026, humanity has launched over 10,000 objects to orbit and beyond. Roughly 60 nations and dozens of private companies operate or have operated spacecraft. The pace of launches has accelerated dramatically since 2015 — SpaceX alone conducts more launches per year than all nations combined did in the 1960s. The missions below represent milestones, scientific achievements, and the most consequential commercial and governmental space programmes.

8. Commercial & New Space
Since 2010, private launch companies have fundamentally changed the economics of space access. SpaceX reduced launch costs by ~10× through reusable rockets. A new wave of commercial stations, lunar landers, and interplanetary vehicles is now in development.
| Year | Mission / Vehicle | Operator | Achievement | Status |
|---|---|---|---|---|
| 2010 | Falcon 9 / Dragon | SpaceX | First commercial ISS resupply (2012). First propulsive booster landing (2015). Crew Dragon first commercial crewed ISS flight (2020). 200+ Falcon 9 launches by 2026. | Active |

9. Failures & Disasters
For every celebrated success, multiple missions have failed — sometimes with the loss of life, sometimes because of software bugs, engineering errors, or units mismatches. These failures shaped safety culture and engineering practice more profoundly than any successes.
Crewed Disasters
| Date | Mission | Crew Lost | Cause | Legacy |
|---|---|---|---|---|
| Jan 27, 1967 | Apollo 1 fire | Gus Grissom, Ed White, Roger Chaffee | Cabin fire during ground test in a pure-oxygen atmosphere. Faulty wiring under Grissom's seat ignited. The inward-opening hatch could not be opened under internal pressure. All three died within minutes. | Program halted 20 months. Complete Apollo capsule redesign: quick-opening hatch, fire-resistant materials, mixed O₂/N₂ atmosphere on the pad. The most impactful safety overhaul in US space history. |
| Jun 30, 1971 | Soyuz 11 | Georgy Dobrovolsky, Vladislav Volkov, Viktor Patsayev | A pressure-equalisation valve opened prematurely during module separation at 168 km altitude. The capsule depressurised in 112 seconds. The crew, not wearing pressure suits (no room in the capsule), were found dead on recovery. The first and only humans to die in space. | Soyuz redesigned to carry only 2 suited cosmonauts. Requirement for suits during ascent/reentry became permanent. Salyut programme redesigned. All subsequent crewed missions worldwide require pressure suits during critical phases. |
| Jan 28, 1986 | Challenger (STS-51-L) | Francis Scobee, Michael Smith, Ronald McNair, Ellison Onizuka, Judith Resnik, Gregory Jarvis, Christa McAuliffe | O-ring seal in the right solid rocket booster failed due to cold temperatures (−3°C at launch, O-rings brittle below 17°C). Hot gases breached the external tank. Orbiter broke apart 73 seconds after launch at 46,000 ft. Engineers had warned against launching in cold weather; management overruled them. | 32-month shuttle standdown. Rogers Commission. O-rings redesigned with heaters. Launch decision process overhauled — engineers now have formal authority to scrub. Christa McAuliffe (Teacher in Space) became a symbol. Normalisation-of-deviance concept enters engineering culture. |
| Feb 1, 2003 | Columbia (STS-107) | Rick Husband, William McCool, Michael Anderson, Kalpana Chawla, David Brown, Laurel Clark, Ilan Ramon | A 750g piece of foam insulation struck the leading edge of the left wing during launch, creating a 15–25 cm hole in the reinforced carbon-carbon panels. During reentry, superheated plasma (~1480°C) entered the wing structure. Vehicle broke apart over Texas and Louisiana at 63 km altitude, travelling at 18× the speed of sound. | 2.5-year standdown. Columbia Accident Investigation Board (CAIB). NASA's risk management culture overhauled. Foam strikes had occurred on previous missions but were not acted upon. Shuttle program retired 2011 partly as result. Kalpana Chawla: first Indian-American in space; memorialised worldwide. |
Robotic Mission Failures
| Year | Mission | Agency | Failure Mode & Cost |
|---|---|---|---|
| 1993 | Mars Observer | NASA | Lost 3 days before Mars orbit insertion. Probable cause: rupture in fuel pressurisation line caused spacecraft to spin uncontrollably. Cost $813M. Led to NASA's "faster, better, cheaper" policy — which then produced two more Mars failures in 1999. |
| 1999 | Mars Climate Orbiter | NASA | Lost at Mars orbit insertion. Root cause: Lockheed Martin's navigation software output thruster data in pound-force·seconds; NASA's trajectory team assumed newton-seconds. The unit mismatch pushed the spacecraft 170 km too low, causing it to burn up in the atmosphere. Cost $327.6M. Considered the most embarrassing units error in engineering history. |
| 1999 | Mars Polar Lander | NASA | Lost during powered descent. Most likely cause: spurious signal from landing leg sensors, generated when legs deployed during descent, falsely indicated touchdown and shut off the engines at ~40 m altitude. Spacecraft crashed at full descent speed. Cost $165M. Part of the "cheaper, faster" failure cluster alongside MCO. |
| 2003 | Beagle 2 | ESA | ESA's Mars lander went silent after separation from Mars Express on Christmas Day 2003. Found on the surface in 2015 by Mars Reconnaissance Orbiter — partially deployed with 2–3 of its 4 solar panel "petals" open, blocking the radio antenna. Probable cause: bounced and collided with a rock, or a petal was damaged during airbag landing. |
| 2016 | Schiaparelli EDM | ESA Roscosmos | ExoMars test lander crashed at ~300 km/h. IMU readings saturated for 1 second; onboard computer concluded it had already landed, jettisoned the parachute, and fired its retrorockets for only ~3 seconds instead of the required 30. The lander was still 3.7 km above the surface. Telemetry was received throughout — the failure was diagnosed precisely. |
| 2019 | Beresheet | SpaceIL (Israel) | First private Moon lander. An inertial measurement unit (IMU) was accidentally switched off during descent, triggering a chain of resets. Main engine could not restart in time. Crashed at ~500 km/h. Reportedly carried a payload of tardigrades and human DNA — location unknown on lunar surface. |
| 2019 | Chandrayaan-2 Vikram | ISRO | Lander entered an uncontrolled roll during powered descent. Software could not correct fast enough. Impacted ~500m from target at ~50 m/s rather than near-zero. Orbiter healthy and operating. ISRO did not release official failure analysis. Cost ~$140M total (lander + orbiter). Chandrayaan-3 successfully landed the same target site in 2023. |
| 2023 | Luna-25 | Roscosmos | Russia's first lunar mission since Luna-24 in 1976. An orbit-correction manoeuvre engine fired for 127 seconds instead of the planned 84 seconds due to a software error. Spacecraft entered an uncontrolled orbit and crashed on the Moon at ~2.5 km/s near the south pole — the very target it was racing to beat Chandrayaan-3 to. India landed 3 days later. |
| 2024 | Peregrine Mission 1 | Astrobotic / NASA CLPS | First commercial US lunar lander under NASA's CLPS programme. A propellant valve failed to close after launch, causing an oxidiser leak. The spacecraft lost ~40% of its propellant within hours and could not achieve a lunar trajectory. Redirected to burn up on Earth reentry 10 days later. Carried 5 NASA science instruments and commercial payloads including human remains. Cost ~$108M in NASA funding. |
