  1. My dear friend, Jennifer. We had so many more adventures ahead of us. I still have things I want to tell you. Especially how much I miss you, and will continue to miss you. Thank you for all of the wonderful memories. I hope you left this world knowing how much you were loved.

    When I come to the end of my journey
    And I travel my last weary mile
    Just forget if you can, that I ever frowned
    And remember only the smile

    Forget unkind words I have spoken
    Remember some good I have done
    Forget that I ever had heartache
    And remember I’ve had loads of fun

    Forget that I’ve stumbled and blundered
    And sometimes fell by the way
    Remember I have fought some hard battles
    And won, ere the close of the day

    Then forget to grieve for my going
    I would not have you sad for a day
    But in summer just gather some flowers
    And remember the place where I lay

    And come in the shade of evening
    When the sun paints the sky in the west
    Stand for a few moments beside me
    And remember only my best

  3. Dear Grassman Family,

    I met Jennifer through my sister Suzanne at least 15 years ago. She shared many a celebration and sadness with our family and I was always happy to see her. I had hoped that she would beat the setback in her recovery from cancer and was terribly saddened to hear of her passing. She was such a beautiful person and I’m grateful I had the chance to know her.

    Sending prayers for strength and peace.

  4. I will miss our morning walks/talks- the timing of which was scheduled around her weather in Texas as mine didn’t get as hot as early in Virginia. She hated my earbuds though because she could hear the traffic near my neighborhood so I would have to put her on speaker lol. She was a great friend and I am so grateful for the time we got to spend together. She will be missed. ❤️🙏🏻

  5. Cousin Jennifer was a wonderful person! Very caring, thoughful and just plain sweet! She will always be remembered!

    She was so instrumental in planning our family reunion along with her sister, Jill! You Will be missed so much but I am glad you are out of pain!

  8. Jennifer was a blessing to work with in the Integrated Communications Group of NASA Flight Operations at Johnson Space Center. We had lots of great discussion about work plus our more personal things. My prayer is that I may see her again in Heaven. Save me a good seat for worshiping our Lord Jesus Christ!

  9. It always brought a smile to my face when I would see Jennifer dialed-in to one of our Orion imagery team meetings. She played a central role helping us coordinate the crew’s onboard displays for controlling the spacecraft cameras. Her expertise and friendly nature always made her a pleasure to work with. Her absence is keenly felt and she will be missed. My sincere condolences and warm wishes to her family as they carry her memory forward.
