DSN is interested in the round trip time - they're both right. How long does it take to ACK the data that was sent? 1.84 days. How old is the data that was sent? 0.92 days (22 hours). Communication protocols at that distance are kind of interesting. Things like dropped data and delays can make it challenging. https://en.wikipedia.org/wiki/Interplanetary_Internet https://en.wikipedia.org/wiki/Interplanetary_Internet https://www.nasa.gov/directorates/heo/scan/engineering/technology/disruption_tolerant_networking_overview https://www.nasa.gov/directorates/heo/scan/engineering/techn... https://ipnsig.org/tag/deep-space-network/ https://ipnsig.org/tag/deep-space-network/ https://www.nytimes.com/1990/10/02/science/spacecraft-passes-a-critical-test.html?unlocked_article_code=hBBXhY68kw4onDAZ8jc8tjxF-ORQ3xyKQyIvfWBEmk1eUMyFXpFK26qBShUdhulioha7gfO7szqFVsg5uDOioXq8QSCCPMQB8xUCObxJiELfJziUUfrVTvzTQciT6WLP8t7bC_hL5McmXeH7tvH7Huqyj__Viv7DcO-IQljkErZrP2mhTXaUnVrlxLZOpZE0qRFxY__Eq7tCCoEdEcCRoTqwcLjDGuuv8xR2cWnNxBd-J2dpSYWsWZicLw1-1yh3aoV0bYWInS86FfmxWF1VhMbG83R_Ef5-uBDkRSe_XQOX46QTdCXpltygGm7ziGBZjvTeyP0JS0OYQtP6zseY3g5cqspn8xLOR9Xm&giftCopy=1_CurrentCopy&smid=url-share https://www.nytimes.com/1990/10/02/science/spacecraft-passes...
