日本私人航天公司Space One于3月5日在和歌山县Kii航天港发射Kairos No. 3火箭，但几分钟后中止了飞行。这标志着该公司第三次受挫，该公司旨在成为首个将卫星送入轨道的日本私人实体。
总部位于东京的初创公司Space One Co.于3月5日上午11:10从和歌山县串本町的Kii航天港发射了其18米高、三级固体燃料Kairos No. 3火箭。然而，升空约一分钟后，直播画面显示火箭开始旋转，五分钟后，公司宣布终止任务，称其“发现任务难以完成”。该火箭携带了包括台湾太空署和日本初创公司在内的五个小型卫星，计划在发射约50分钟后将其部署到约500公里高度的轨道上。
X平台上对Space One Kairos No. 3火箭失败的反应突显了对连续第三次挫折的失望、对日本私人轨道发射能力的怀疑，以及将失败视为学习机会的支持性情绪。知名航天账户报告了上升阶段的异常，而用户则引用火箭历史鼓励坚持。公司社长坚称这不是失败，不会影响未来的发射。

失敗して失敗して、外国からは日本人に国産ロケットは飛ばせないんだよ、外国の助っ人入れれば良いさHAHAHAって言われていた時期があったのよ
近いうちにカイロスロケットも第3の国産ロケットシリーズに名を連ねるさ
カイロス３号機🚀ミッション失敗でもやっぱり大空に飛び立つ姿は感動した‼️

The Federal Aviation Administration (FAA) has grounded Blue Origin's New Glenn rocket following a partial failure during its third mission, NG-3, launched Sunday from Cape Canaveral Space Force Station. An upper-stage engine issue prevented the BlueBird 7 satellite from reaching its target 285-mile orbit, achieving only about 95 miles. This incident, the second grounding for the rocket, will halt flights pending investigation.
Tokyo-based space startup Space One canceled the launch of its Kairos No. 3 small rocket shortly before liftoff on March 4 from Spaceport Kii in Kushimoto, Wakayama Prefecture, after a safety system activated. The launch was scheduled for 11 a.m., but halted 30 seconds prior. The company plans a press conference that afternoon to explain the incident.

Japan's private space company Space One canceled the launch of its third Kairos small rocket on Sunday due to unfavorable weather conditions. This setback delays the company's effort to become the first Japanese private firm to place satellites into orbit using a domestically developed rocket. The attempt scheduled for Wednesday last week was also postponed for the same reason.
Amid strained alliances with the United States, countries including Germany, Spain, and Canada are committing significant funds to develop independent rocket programs for national security. These efforts aim to reduce reliance on foreign launch providers like SpaceX. The investments support startups working toward orbital launches in the coming years.

NASA Administrator Jared Isaacman announced the Ignition initiative on March 24, canceling the Lunar Gateway orbiting station to focus on a $20 billion three-phase moon base on the lunar surface. The shift, echoing Trump administration budget proposals, supports frequent Artemis crewed landings amid competition from China and preparations for the first crewed Artemis mission with a launch window opening April 1.
Orion spacecraft from Artemis 2 mission has completed its final maneuver before atmospheric reentry, the most critical phase of the journey. Astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen face a 13-minute descent at over 40,000 km/h and temperatures above 2,500 degrees, with splashdown planned off San Diego.

NASA has delayed the Artemis II mission to April 1 following a helium flow problem that rolled the rocket back from the pad, building on prior fixes for hydrogen leaks during fueling tests. This first crewed lunar orbit since 1972 faces ongoing maintenance before returning to the launch site.
